Corporate Governance, Firm Age, and Leverage: Empirical Evidence from China

This study aims to analyze the influence of corporate governance on firm leverage. It also investigates the moderating effect of firm age on the association between corporate governance and leverage. Using a sample of Chinese listed firms, it addresses several issues that have been identified in the prior literature regarding capital structure. This study provides novel findings which reveal that CEO duality and board commissions have a statistically significant role in determining the leverage levels for NSOEs, however, the positive effect of board commissions established on leverage decreases as the firm ages. Board size, board independence and supervisory boards influence the leverage levels for SOEs, however, the negative effects of board independence and supervisory boards on leverage reduce as the firm grows older. Keywords: Corporate governance, leverage, firm age, Chinese listed firms DOI: 10.7176/RJFA/10-2-0

Promoting female participation in professional development programmes

A recent publication of the Ministry of Education, Islamabad, shows that the province of Sindh has a population of over 30 million. The overall literacy rate in this province is 46.7 %, while the female literacy rate is 35.4%. However, in the rural areas of Sindh the female literacy rate is 13.11% against the male literacy rate of 52.1%. There are many social, cultural and economic factors that inhibit females from availing opportunities on an equal basis with the other segments of society. The literature also reveals that due to the above-mentioned factors females are confined to play a passive role in general and in the education sector in particular. According to a recent UNDP publication, there is considerable disparity between males and females in terms of professional development. Considering the importance of professional development of females in the education sector in Sindh, the Aga Khan University Institute for Educational Development (AKU-IED), under the Pakistan Non- Government Initiatives (PNI-II), took an initiative to launch a project titled ‘Strengthening the Capacity of NGOs/CBOs’. The project targeted to provide opportunities of professional development to 258 individuals, but the actual number of those who graduated was 388, considerably exceeding the planned target. Out of 388, 68 % (262) were females, which show the enthusiasm and commitment of the participants, collaborating NGOs/CBOs and AKU-IED towards the professional development of females. Through this initiative, females were trained as ‘agents of change’ to motivate their communities towards education of their children, in particular the girl child. This presentation unfolds the learning experiences of the USAID Project-III team in promoting female participation in professional development programmes at AKU-IED

A Novel Feature-Selection Algorithm in IoT Networks for Intrusion Detection

The Internet of Things (IoT) and network-enabled smart devices are crucial to the digitally interconnected society of the present day. However, the increased reliance on IoT devices increases their susceptibility to malicious activities within network traffic, posing significant challenges to cybersecurity. As a result, both system administrators and end users are negatively affected by these malevolent behaviours. Intrusion-detection systems (IDSs) are commonly deployed as a cyber attack defence mechanism to mitigate such risks. IDS plays a crucial role in identifying and preventing cyber hazards within IoT networks. However, the development of an efficient and rapid IDS system for the detection of cyber attacks remains a challenging area of research. Moreover, IDS datasets contain multiple features, so the implementation of feature selection (FS) is required to design an effective and timely IDS. The FS procedure seeks to eliminate irrelevant and redundant features from large IDS datasets, thereby improving the intrusion-detection system’s overall performance. In this paper, we propose a hybrid wrapper-based feature-selection algorithm that is based on the concepts of the Cellular Automata (CA) engine and Tabu Search (TS)-based aspiration criteria. We used a Random Forest (RF) ensemble learning classifier to evaluate the fitness of the selected features. The proposed algorithm, CAT-S, was tested on the TON_IoT dataset. The simulation results demonstrate that the proposed algorithm, CAT-S, enhances classification accuracy while simultaneously reducing the number of features and the false positive rate.publishedVersio

Detection and prevention of Denial-of-Service in cloud-based smart grid

Smart Grid (SG), components with historical set of security challenges, becomes more vulnerable because Information and Communications Technology (ICT) has its own share of problems while Cloud infrastructure adds yet another unpredicted layer of threats. Scalability and availability, which are strong aspects of the cloud platform making it attractive to users, also attracts security threats for the same reasons. The malware installed on single host offers very limited scope compared to attack magnitude that compromised Cloud platform can offer. Therefore, the strongest aspect of Cloud itself becomes a nightmare in Cloud-Based SG. A breach in such a delicate system can cause severe consequences including interruption of electricity, equipment damage, data breach, complete blackouts, or even life-threatening consequences. We mimic Denial-of-Service (DoS) attacks to demonstrate interruption of electricity in SG with open-source solution to co-simulate power and communication systems

Impact of a community-based perinatal and newborn preventive care package on perinatal and neonatal mortality in a remote mountainous district in Northern Pakistan

Background: There is limited evidence from community-based interventions to guide the development of effective maternal, perinatal and newborn care practices and services in developing countries. We evaluated the impact of a low-cost package of community-based interventions implemented through government sector lady health workers (LHWs) and community health workers (CHWs) of a NGO namely Aga Khan Health Services on perinatal and neonatal outcomes in a sub-population of the remote mountainous district of Gilgit, Northern Pakistan. Methods: The package was evaluated using quasi experimental design included promotion of antenatal care, adequate nutrition, skilled delivery and healthy newborn care practices. Control areas continued to receive the routine standard health services. The intervention areas received intervention package in addition to the routine standard health services. Outcome measures included changes in maternal and newborn-care practices and perinatal and neonatal mortality rates between the intervention and control areas. Results: The intervention was implemented in a population of 283324 over a 18 months period. 3200 pregnant women received the intervention. Significant improvements in antenatal care (92% vs 76%, p \u3c .001), TT vaccination (67% vs 47%, p \u3c .001), institutional delivery (85% vs 71%, p \u3c .001), cord application (51% vs 71%, p \u3c .001), delayed bathing (15% vs 43%, p \u3c .001), colostrum administration (83% vs 64%, p \u3c .001), and initiation of breastfeeding within 1 hour after birth (55% vs 40%, p \u3c .001) were seen in intervention areas compared with control areas. Our results indicate significant reductions in mortality rates in intervention areas as compared to control areas from baseline in perinatal mortality rate (from 47.1 to 35.3 per 1000 births, OR 0.62; 95% CI: 0.56-0.69; P 0.02) and neonatal mortality rates (from 26.0 to 22.8 per 1000 live births, 0.58; 95% CI: 0.48-0.68; P 0.03). Conclusions: The implementation of a set of low cost community-based intervention package within the health system settings in a mountainous region of Pakistan was found to be both feasible and beneficial. The interventions had a significant impact in reduction of the burden of perinatal and neonatal mortality

Demand Side Management Techniques for Home Energy Management Systems for Smart Cities

In this paper, three distinct distributed energy resources (DERs) modules have been built based on demand side management (DSM), and their use in power management of dwelling in future smart cities has been investigated. The investigated modules for DERs system are: incorporation of load shedding, reduction of grid penetration with renewable energy systems (RES), and implementation of home energy management systems (HEMS). The suggested approaches offer new potential for improving demand side efficiency and helping to minimize energy demand during peak hours. The main aim of this work was to investigate and explore how a specific DSM strategy for DER may assist in reducing energy usage while increasing efficiency by utilizing new developing technology. The Electrical Power System Analysis (ETAP) software was used to model and assess the integration of distributed generation, such as RES, in order to use local power storage. An energy management system has been used to evaluate a PV system with an individual household load, which proved beneficial when evaluating its potential to generate about 20–25% of the total domestic load. In this study, we have investigated how smart home appliances’ energy consumption may be minimized and explained why a management system is required to optimally utilize a PV system. Furthermore, the effect of integration of wind turbines to power networks to reduce the load on the main power grid has also been studied. The study revealed that smart grids improve energy efficiency, security, and management whilst creating environmental awareness for consumers with regards to power usage

Effect and feasibility of district level scale up of maternal, newborn and child health interventions in Pakistan: A quasi-experimental study

Introduction: Pakistan has a high burden of maternal, newborn and child morbidity and mortality. Several factors including weak scale-up of evidence-based interventions within the existing health system; lack of community awareness regarding health conditions; and poverty contribute to poor outcomes. Deaths and morbidity are largely preventable if a combination of community and facility-based interventions are rolled out at scale.Methods and analysis: Umeed-e-Nau (UeN) (New Hope) project aims is to improve maternal, newborn and child health (MNCH) in eight high-burden districts of Pakistan by scaling up of evidence-based interventions. The project will assess interventions focused on, first, improving the quality of MNCH care at primary level and secondary level. Second, interventions targeting demand generation such as community mobilisation, creating awareness of healthy practices and expanding coverage of outreach services will be evaluated. Third, we will also evaluate interventions targeting the improvement in quality of routine health information and promotion of use of the data for decision-making. Hypothesis of the project is that roll out of evidence-based interventions at scale will lead to at least 20% reduction in perinatal mortality and 30% decrease in diarrhoea and pneumonia case fatality in the target districts whereas two intervention groups will serve as internal controls. Monitoring and evaluation of the programme will be undertaken through conducting periodical population level surveys and quality of care assessments. Descriptive and multivariate analytical methods will be used for assessing the association between different factors, and difference in difference estimates will be used to assess the impact of the intervention on outcomes.Ethics and dissemination: The ethics approval was obtained from the Aga Khan University Ethics Review Committee. The findings of the project will be shared with relevant stakeholders and disseminated through open access peer-reviewed journal articles
